Reorganize examples into topic-based subfolders
Move 304 examples from a flat numbered directory into 14 descriptive subfolders: getting-started, services (speech + function-calling), transcription, vision, realtime, persistent-context, context-summarization, update-settings (stt/tts/llm), turn-management, thinking-and-mcp, transports, video-avatar, video-processing, and features. Strip numbered prefixes from filenames (e.g. 07c-interruptible-deepgram.py becomes services/speech/deepgram.py) since the folder context makes them redundant. Keep numbered prefixes only in getting-started/ where ordering matters. Update eval script paths and README to match the new structure.

"""Grok Realtime persistent context example.
|
||||
|
||||
This example demonstrates how to save and load conversation history with
|
||||
Grok's Realtime Voice Agent API. It allows:
|
||||
- Saving the current conversation to a JSON file
|
||||
- Loading a previous conversation from disk
|
||||
- Listing all saved conversation files
|
||||
|
||||
This is useful for building voice agents that remember past conversations.
